Well neo79, guess what (don't laugh ya), for now (these two words are very important key words), I'm running the Dyns active, right off my Alpine CDA-9833 built-in internal amp, just wondering how the Dyns will sound like without an amp, and since I always take things one step at a time, sometimes half a step... Luckily I'm running it active, as expected, the internal amps do not like to drive the 3" diameter voice coils... hafta set the tweeter level some 6dB down just to compensate and balance the sound... and the mid bass is thin, expected. well, don't start heavily racuning me with amps yet, although some suggestions are welcomed...
